Struct PermutationSolutionBuilder 

pub struct PermutationSolutionBuilder { /* private fields */ }

Builder for permutation-based solutions (Solution<usize>).

Typical use case: routing problems like TSP.

Implementations

impl PermutationSolutionBuilder

pub fn new(size: usize) -> Self

Creates an identity permutation [0, 1, 2, ..., size-1].

pub fn from_variables(variables: Vec<usize>) -> Self

Creates a builder from an existing permutation vector.

pub fn with_variables(self, variables: Vec<usize>) -> Self

Replaces the permutation vector.

pub fn with_quality(self, quality: f64) -> Self

Sets optional scalar quality.

pub fn swap(self, i: usize, j: usize) -> Self

Swaps two positions if both indexes are valid.

pub fn build(self) -> Solution<usize>

Builds the final permutation solution.
